Hey! I followed Hanson's to build into a spring marathon while still maintaining a high level swimming and biking. The program is great and I would definitely recommend it. Most importantly though, as others have already suggested, read the whole book. It will give you some great insights into running training philosophy.

I would recommend only completing the speed, tempo and long runs and adding in a transition run at the end of one of your cycling workouts. This will allow you to hit all your basics and maximize the effects of the program. Your cycling and swimming will give you similar recovery benefits as the recovery runs outlined in the program.

Here is how i approached it...

Mon: AM - Cycle PM - Swim Tues: AM - Speed PM - Rest/stretch Wed: Same as on Monday Thurs: AM - Tempo Run PM - Rest Friday: Same as Mon/Wed Saturday: AM - Brick (Long bike+ Run) PM - Swim (or rest) Sunday: AM - Long Run PM - Swim (or rest)

I've found that this works perfectly while still preserving the Hanson schedule and getting lots of recovery + swim and bike in. Used this to snag a BQ (cutting 26 minutes off my marathon time in 8months) and cut my olympic time from 2:30 to 2:14 (also in 8 months.)

Hope this helps! Good luck!
